Silver halide color photographic film element having a thermoplastic support capable of being marked by means of a laser

Abstract

A silver halide color photographic film element and more particularly a color motion picture projection film element is provided comprising a transparent thermoplastic film support having a subbing layer unit, coated thereon at least one color forming hydrophilic layer and protective layer, characterized in that at least said subbing layer unit comprises at least one light-stabilizer, preferably absorbing ultraviolet radiation, and at least one chemical compound having reducing properties.

We claim: 
     
       1. A silver halide photographic motion picture projection film element which upon being exposed and color processed can be marked for subtitling purposes by a laser beam, said element comprising a transparent polyethylene terephthalate film support having a subbing layer unit and coated thereon, in succession, a blue-sensitive silver halide emulsion layer comprising a yellow-forming coupler, an intermediate layer, a red-sensitized silver halide emulsion layer comprising a cyan-forming coupler, an intermediate layer, a green-sensitized silver halide emulsion layer comprising a magenta-forming coupler and an anti-stress layer, said subbing layer unit further comprising at least one light-sensitive stabilizer and at least one chemical compound having reducing properties which is an oxidant and/or a flame retarding agent selected form the group of compounds consisting of phosphites having the general formula O═P(OR) 3  ; organic sulfides R--S--R and sterically hindered phenols, R representing therein an alkyl or an aryl group and wherein said light-stabilizer is a benzophenone compound absorbing ultraviolet radiation, said sterically hindered phenols being selected from the group consisting of di-esters of di-t-butylphenol and 2,5-dialkylester substituted hydroquinone and said element being laser ablatable without detriment to said film element. 
     
     
       2. A film element according to claim 1, wherein said subbing layer unit has coated between the blue-sensitive silver halide emulsion layer and the transparent support a yellow antihalation undercoat which comprises at least one yellow non-diffusing dye that absorbs blue light and is removable and/or decolorizable in a processing bath. 
     
     
       3. A film element according to claim 2, wherein between said blue-sensitive silver halide emulsion layer and said red-sensitized silver halide emulsion layer a bluish antihalation intermediate layer is provided, which comprises at least one blue non-diffusing dye that absorbs red light and is removable and/or decolorizable in a processing bath. 
     
     
       4. A film element according to claim 1, wherein said light-stabilizing agent absorbing ultraviolet radiation is selected from the group of benzophenone compounds consisting of 2-hydroxy-4-methoxy-benzophenone and 2,4-di-hydroxy-benzophenone. 
     
     
       5. A film element according to claim 1, wherein said subbing layer unit is substantially composed of at least one hydrophobic layer directly contacting the transparent film support and at least one hydrophilic colloid layer coated thereupon. 
     
     
       6. A film element according to claim 5, wherein said hydrophobic layer has a composition selected from the group consisting of vinylidene chloride and styrene/butadiene copolymers. 
     
     
       7. A film element according to claim 5, wherein said hydrophilic colloid layer is a gelatinous layer. 
     
     
       8. A film element according to claim 5, wherein said hydrophilic colloid layer is hardened with a vinyl sulphonyl hardener and/or with a triazine hardener. 
     
     
       9. A film element according to claim 5, wherein said hydrophilic colloid layer comprises said light-stabilizer and said chemical compound having reducing properties.
